Vehicle scheduling method for junction without signal lights in autonomous driving environment

Abstract

The invention provides a vehicle scheduling method for a junction without signal lights in an autonomous driving environment. The method includes that communication requests of a vehicle are transmitted to an RSU (remote subscriber unit) and form communication request sets, and the communication request sets are sequenced in an ascending manner according to scheduled time when the vehicle reachesthe junction; the RSU updates intermediate times of the vehicle according to the nearest vehicle allocation time and nearest vehicle belonging road segment, and the communication request sets are constructed to optimize the vehicle allocation time; the RSU traverses the communication request sets of the vehicle allocation time, the allocation time of the vehicle passing through the junction is calculated, and the intermediate time of the vehicle is updated; the head end of the vehicle reaches the junction at the time allocated by the RSU, the vehicle leaves finally, and the RSU updates the vehicle allocation time and the vehicle belonging road section; the RSU schedules all the vehicles corresponding to the communication requests in the communication request sets to pass through the junction. Compared with the prior art, the vehicle scheduling method has the advantages that time for the vehicles passing through the junction is integrally reduced.

Description

technical field [0001] The invention relates to the research field of vehicle control technology at road intersections, in particular to a method for dispatching vehicles without signal lights at intersections in an automatic driving environment. Background technique [0002] For a long time, the way of signal light control is the way of vehicle scheduling at most urban road intersections. With the development of intelligent transportation systems, signal light control technology that can adaptively allocate signal light phases and cycles according to traffic flow has also been promoted and applied in many cities. However, even adaptive intersection signal dispatching systems such as SCATS or SCOOTS, due to the limitations of detection means and traditional signal control conditions, have limited effect on alleviating urban traffic congestion. traffic needs. [0003] At present, the Internet of Vehicles and autonomous driving technologies are developing rapidly, and there ...
